Purpose To investigate the abnormal brain development in fetuses with isolated mild to moderate ventriculomegaly(VM)during the second and third trimesters of pregnancy by using semi-quantitative fetal total maturation score(fTMS).Materials and Methods A retrospective analysis was performed on 45 normal fetuses and 78 abnormal fetuses who underwent fetal MRI in the General Hospital of Ningxia Medical University from January 2018 to October 2022.fTMS was used to score all images.Linear regression was used to assess the relationship between fTMS and gestational age between normal and abnormal fetuses and to analyze the differences between fetuses with isolated mild and moderate VM and controls.Results In the control group,fetal fTMS was significantly positively correlated with gestational age(r=0.939,P<0.05).The linear regression equation between fTMS(Y)and gestational age(X)was as follows:Y=-28.1+1.25X.In the mild and moderate isolated VM groups,fTMS was positively correlated with gestational age(r=0.945,0.906,P<0.05).The linear regression equations of fTMS(Y)and gestational age(X)were:Y=-28.46+1.24X,Y=-25.57+1.13X.The average fTMS of healthy fetus,mild VM and moderate VM were(10.55±4.25)points,(10.13+4.08)points and(9.22±3.77)points,respectively.There was no significant difference in fTMS between the 49 fetuses with mild isolated VM and the control group(t=1.651,P>0.05).There was significant difference in fTMS between the 29 fetuses with moderate isolated VM and the control group(t=2.306,P<0.05).Conclusion fTMS is suitable for routine clinical use and sensitive to differences in brain maturation between fetuses with isolated moderate VM and healthy controls.

Hundred years of development of surgery have laid the foundation and principles of modern surgery.As a result,surgical oncology has also been rapidly developing and updating,and the surgical principles and techniques have become increasingly mature.The quality of surgical oncology is closely related to the prognosis of patients,and the effectiveness of surgical oncology can be improved through accurate preoperative resectability assessment,neoadjuvant therapy,standardized tumor R0 resection and multidisciplinary team(MDT).Through meticulous preoperative preparation,precise intraoperative operation,excellent postoperative management,and orderly development of new surgical technologies,we are able to enhance the safety of surgical oncology.

Objective To investigate the current status of knowledge-attitude-practice of cardiac rehabilitation in patients undergoing coronary artery bypass grafting(CABG) and analyze its influencing factors. Methods From July to November 2022, 288 patients with CABG in the coronary heart disease surgery center of Beijing Anzhen Hospital Affiliated to Capital Medical University were conveniently included, and general information questionnaire and cardiac rehabilitation knowledge and practice questionnaire were used to investigate the general situation and the level of knowledge-attitude-practice of cardiac rehabilitation in patients with coronary heart disease. Results A total of 290 questionnaires were sent out in this study, and 288 were effectively collected, with an effective recovery rate of 99.31%. The total score of the questionnaire was (106.81±13.35), and the total score rate was 62.83%, including the knowledge questionnaire scoring (39.34±9.13), belief questionnaire scoring (32.86±3.39) and behavior questionnaire scoring (34.61±3.54). The scoring rates of knowledge, attitude and practice questionnaire were 46.28%, 82.15% and 76.91%, respectively. Multiple linearregression analysis showed that patients who lived in rural areas, had education background of primary school or below, were farmers, had public health insurance, and had no previous coronary intervention, had lower levels of knowledge-attitude-practice of cardiac rehabilitation (P < 0.05). Conclusion The knowledge-attitude-practice of cardiac rehabilitation, especially the level of knowledge, in patients with CABG is needed to be improved. The factors that affect the level of knowledge-attitude-practice of cardiac rehabilitation in this population are diversified, suggesting that individual cardiac rehabilitation guidance should be implemented according to different people and local conditions, and diversified cardiac rehabilitation models should be established to improve the long-term and compliance of cardiac rehabilitation.

Objective:To describe the long-term characteristics and trend changes in the incidence and mortality of female breast cancer in Shanghai from 1 973 to 2017,aiming to provide references for exploring the etiology of breast cancer and formulating strategies and measures for prevention,intervention and control. Methods:Joinpoint software was used to analyze the trend changes in the incidence and mortality of female breast cancer in Shanghai from 1 973 to 2017,and an age-period-cohort model was constructed to explore the effects of age,year of diagnosis,and birth cohort on long-term trend changes. Results:From 1 973 to 2017,there were 68 192 new cases of female breast cancer in Shanghai,with a diagnosed rate of 31.72/100 000.The incidence rate continued to rise,and the risk of the disease continued to rise from the age of 20 years,and the rise rate accelerated significantly after the age of 40 years.There were 21 535 female breast cancer deaths from 1 973 to 2017.The mortality rate was stable,with a death rate of 8.62/100 000,and the risk of death increased significantly from the age of 45 years.The effects of age,period and cohort had a significant impact on the incidence of breast cancer(P＜0.01),while the increase in mortality rate was related to age and cohort effects(P＜0.01). Conclusion:The incidence rate of female breast cancer in Shanghai is still rising rapidly,and the mortality trend is generally stable,suggesting that the treatment is effective and the quality of life is improved.However,breast cancer is still the main malignant tumor among females in Shanghai.It should be continued to implement prevention and control strategies such as lifestyle intervention and screening of high-risk individuals to further strengthen the prevention and control of breast cancer.

Objective:To describe the epidemiological features and temporal trends of colorectal cancer in urban Shanghai from 1973 to 2017. Methods:Data on colorectal cancer in urban Shanghai was obtained through Shanghai Cancer Registry and Vital Statistics System.Joinpoint analysis was used to describe the temporal trends and annual percent change(APC)and age-period-cohort analysis was used to estimate the association between age,period and birth cohort and colorectal cancer. Results:A total of 105 847 cases and 60 447 deaths of colorectal cancer were diagnosed in urban Shanghai over the 45-year study period.Both the number of new cases and the number of deaths showed an increasing trend.In the same period,the age-standardized incidence of colorectal cancer in urban areas of Shanghai increased significantly from 14.1/100 000 in 1973 to 27.7/100 000 in 2017,while the age-standardized mortality rate increased from 8.2/100 000 to 10.7/100 000.The overall average annual age-standardized incidence and mortality rates were 20.4/100 000 and 11.0/100 000,respectively.With the increase of age,the age-standardized morbidity and mortality of colorectal cancer showed an obvious upward trend.Taking 1993-1997 as reference,the risk of colorectal cancer in Shanghai reached the highest in 2013-2017,and the corresponding relative risk was 1.2(95％confidence interval:1.2-1.3),while the lowest was 0.9(95％confidence interval:0.8-1.0)during 1973-1977.Mortality risk,on the contrary,decreased with the increase of time.Before 1953-1957,the risk of colorectal cancer in urban Shanghai increased with the increase of birth cohort time,and then showed a downward trend.There was a corresponding decline in the risk of colorectal cancer death among people born after 1957. Conclusion:The incidence and mortality of colorectal cancer in Shanghai showed an increasing trend from 1973 to 2017,but the prevalence trend of colorectal cancer is still different among different populations.

Neurofibromatosis type 1 is a progressive autosomal dominant inherited disease caused by a mutation in neurofibromin 1(NF1)gene located on chromosome 1 7q1 1.2.NF1 can cause systemic peripheral neuropathy,but the clinical manifestations are varied due to the different onset times and lesion sites in different patients.The treatment of NF1 involves multiple disciplines due to different lesion sites.Clinical monitoring and symptomatic treatment are the main methods for NF1 management,while radical treatment is difficult.New drugs targeted at the pathogenic gene-related signaling pathways are expected to improve the therapeutic effect for NF1.This review summarizes the progress in the basic research and clinical diagnosis and treatment of NF1.

Objective:To investigate the application of three-dimensional image reconstruction combined with problem-based learning (PBL) in the teaching of physicians receiving continuing education in thoracic surgery.Methods:A total of 68 physicians who received continuing education in Department of Thoracic Surgery in our hospital were selected as research subjects, and they were divided into control group and observation group using a random number table, with 34 physicians in each group. The physicians in the control group received traditional teaching, while those in the observation group received three-dimensional image reconstruction combined with PBL teaching. A questionnaire survey, theoretical assessment, and assessment of practical skills were performed to evaluate the effect of teaching. SPSS 22.0 was used to perform the t-test. Results:Compared with the control group, the observation group had significantly higher degrees of satisfaction with each item of the questionnaire survey ( P<0.05). Compared with the control group, the observation group had significantly higher scores of theoretical assessment [(94.07±6.03) vs. (86.34±5.46), P<0.001] and the assessment of practical skills [(95.20±5.48) vs. (84.71±6.14), P<0.001]. Conclusion:The application of three-dimensional image reconstruction combined with PBL teaching can help to improve the comprehensive ability of physicians receiving continuing education.
